XC9536XL-7PC44C 概要

The Xilinx XC9536XL-7PC44C is a high-performance, in-system-programmable CPLD with 36 macrocells, 34 user I/O pins, 800 usable gates, and a 44-pin PLCC package designated QCCJ. It operates from 3.3 V, supports at least 10,000 program-and-erase cycles, and is built on 0.35 µm CMOS technology. The -7 speed designation corresponds to a 178.6 MHz device rating, while the C suffix identifies the commercial temperature grade.

A complex programmable logic device, or CPLD, is a user-programmable semiconductor that combines a flexible logic architecture with nonvolatile configuration storage. CPLDs occupy the middle ground between simple programmable logic arrays and larger FPGAs. They are commonly used for glue logic, bus decoding, interface adaptation, state machines, address decoding, and control logic that benefits from fast deterministic routing and in-system reconfiguration.

The XC9536XL architecture provides 54V18 function blocks, 36 macrocells, and approximately 800 usable gates. Its 34 I/O pins support the integration of multiple control and data signals in a compact device. In-system programmability allows the configuration memory to be updated while the circuit remains operational, making the CPLD useful for field upgrades, production programming, and prototype refinement without replacing the device.

The XC9536XL-7PC44C uses 3.3 V CMOS technology and is specified in a 44-pin J-lead PLCC package with a square package code of QCCJ. Its 5 ns propagation-delay value provides deterministic behavior for control logic, while the 178.6 MHz speed rating supports clocked state machines and moderately timed interface functions. The commercial grade and 0.35 µm process place this device in a mature programmable-logic family.

Typical applications include industrial control interfaces, peripheral bus decoding, instrumentation logic, embedded-system address translation, data acquisition control, and legacy platform consolidation. The 34-I/O count makes the device especially suitable for designs that need more logic than a small GAL or simple microcontroller output can provide, without requiring a large FPGA.

PCB design should preserve the PLCC footprint and route programming and control signals away from high-speed or switching nodes. Use the manufacturer pin description table when assigning tracks, confirm decoupling requirements from DS058, and validate every external interface against the selected I/O standard. Because the device is lead-containing and RoHS non-compliant, its regulatory status must be considered for new commercial and export-sensitive designs.

This page combines the device architecture, verified specifications, package details, drop-in alternatives, comparison data, and practical implementation guidance to support design selection, footprint verification, sourcing, and lifecycle-risk assessment.

🔧

Peripheral Bus Interface Control

The XC9536XL-7PC44C can implement state machines, chip-select generation, and protocol translation for a 3.3 V peripheral bus. Its 36 macrocells provide enough logic for multi-cycle sequencing, and in-system programming permits firmware or configuration revisions without replacing the device. The 44-pin PLCC footprint also supports repair and legacy-system consolidation. Designers should define bus ownership in the design tool, include contention-safe tri-state behavior, and validate propagation timing against the slowest participating peripheral.

Where can I download the XC9536XL-7PC44C datasheet PDF?

The official manufacturer document is AMD datasheet DS058, titled XC9536XL High Performance CPLD. It is available from the AMD documentation link on this page and contains the XC9536XL architecture, operating information, package details, and ordering information. According to that document, revision 1.8 was released on March 21, 2006. Use DS058 rather than generic CPLD guides when validating pin assignments, timing, and electrical limits.

Where can I find the XC9536XL pinout?

The XC9536XL pinout is documented in the pin-description and package-drawing sections of AMD datasheet DS058. The XC9536XL-7PC44C uses a 44-pin J-lead PLCC package, designated QCCJ, with 34 user I/O pins and the remaining terminals assigned to power, ground, configuration, and dedicated functions. Use the manufacturer pin table when assigning PCB tracks because PLCC terminal numbering must follow the physical package drawing rather than a generic connector numbering convention.

Can XC9536XL-7PC44C be programmed while operating?

Yes. The XC9536XL supports in-system programming, which allows its configuration memory to be rewritten while the device operates in the target circuit. AMD datasheet DS058 specifies a minimum of 10,000 program-and-erase cycles for this operating mode. In-system programming supports production programming, field upgrades, and logic revisions, although the design must include the required programming interface and comply with the voltage and signal-sequence requirements in the datasheet.

XC9536XL-7PC44C vs XC9536XL-7PC44I - which is better?

The XC9536XL-7PC44I is the better choice when the existing board requires the industrial temperature grade; the XC9536XL-7PC44C is designated for commercial temperature operation. Both retain the 36-macrocell XC9536XL architecture, 34 I/O pins, 7 ns speed designation, and 44-pin PLCC footprint. According to AMD datasheet DS058, the functional architecture is unchanged, so system firmware and board routing can be reused when the operating-temperature requirement permits.

When should I choose XC9536XL-7PC44C over XC9536XL-5PC44C?

Choose XC9536XL-7PC44C when design timing requires the faster 7 ns device rather than the 5 ns XC9536XL-5PC44C. Both parts use the same 36-macrocell, 34-I/O architecture and 44-pin PLCC format, so the footprint and programming arrangement remain compatible. The XC9536XL-5PC44C may be considered when the faster speed grade is unnecessary, but confirm the complete timing and power characteristics in AMD datasheet DS058 before substitution.

Is XC9536XL-7PC44C suitable for industrial control logic?

The XC9536XL-7PC44C is suitable for control applications that remain within the commercial temperature grade, because the C suffix identifies commercial-grade operation. It combines 36 macrocells with 34 I/O pins and a deterministic 5 ns propagation delay, which suits address decoding, sequencing, and interface control. If ambient conditions exceed the commercial-grade limits, select the XC9536XL-7PC44I industrial variant instead of using the C-suffixed device.

What is the best drop-in replacement for XC9536XL-7PC44C?

The XC9536XL-7PC44I is the closest drop-in replacement when industrial-temperature operation is acceptable or required. It preserves the 7 ns speed grade, 36-macrocell architecture, 34 I/O pins, and 44-pin PLCC footprint while changing the temperature grade. The XC9536XL-7PCG44C is another footprint-compatible option for a lead-free assembly, and the XC9536XL-5PC44C or -10PC44C can be considered only after checking timing margins and power requirements.

Can XC9536XL-7PCG44C replace XC9536XL-7PC44C?

The XC9536XL-7PCG44C can serve as a footprint-compatible alternative when its lead-free assembly configuration is acceptable. It retains the XC9536XL 7 ns device architecture and 44-pin package family, allowing the same board-level layout to be used. Confirm the ordering-code interpretation, terminal assignments, and electrical characteristics in AMD datasheet DS058, and verify whether your assembly process permits the alternate lead-free termination configuration.

What is the AMD equivalent for XC9536XL-7PC44C?

The closest AMD-origin same-family options are the XC9536XL-7PC44I and XC9536XL-7PCG44C. The I suffix changes the temperature grade, while the G suffix denotes the lead-free assembly option. Both belong to the same XC9536XL family and use the 44-pin PLCC package arrangement. Because AMD documentation DS058 covers the family rather than a separate cross-brand replacement matrix, the appropriate grade or assembly variant should be selected according to environmental and manufacturing requirements.

Where can I buy XC9536XL-7PC44C and check its price?

Use the Request a Quote form on this page to request current XC9536XL-7PC44C price, stock status, lead time, and minimum order quantity. The part is a mature PLCC CPLD, so availability can vary by lot and package condition. Provide the target quantity, assembly method, and required delivery date with the request. XAIPART can then confirm the current channel position without relying on a static price that may become outdated.

What is the lead time and stock status of XC9536XL-7PC44C?

Current stock and lead time for the XC9536XL-7PC44C should be confirmed through the Request a Quote form on this page. The CPLD is an older commercial-grade device in a 44-pin PLCC package, so quantity break timing may differ from current mainstream programmable-logic products. Include the required order quantity, target date, and whether the part will be used in a new assembly or replacement repair so that an actionable availability response can be returned.

Is XC9536XL-7PC44C currently in stock?

Current XC9536XL-7PC44C inventory is not represented by a fixed stock statement because availability for mature CPLDs can change by lot. Submit a Request a Quote request with the required quantity and assembly date to obtain a current availability response. Include whether the order requires original factory packaging, inspection records, or a programmed configuration file, since those requirements can materially affect the available supply channel.

What are the power and thermal considerations for XC9536XL-7PC44C?

Power dissipation depends on the selected I/O states, operating frequency, supply voltage, and output loading, so a single heat-sink requirement cannot be stated without those conditions. AMD datasheet DS058 contains the device-specific supply-current and power characteristics. In a PLCC implementation, provide the specified decoupling and preserve package thermal paths; avoid placing the device beside unregulated switching components that raise the local ambient temperature.

エンジニアリング参考データ: XC9536XL-7PC44C — 比較、設計ガイダンス、コンプライアンス情報。

選定ガイド

Choose the XC9536XL-7PC44C when maintaining an existing 3.3 V, 44-pin PLCC design that requires the -7 timing grade and commercial-temperature operation. Select the XC9536XL-7PC44I when the same electrical and timing configuration must operate in an industrial environment. Select the XC9536XL-7PCG44C when a lead-free assembly variant is needed without changing the core speed class. Consider the XC9536XL-5PC44C only when its slower timing still satisfies every setup, hold, and system-level timing requirement. The XC9536XL-10PC44C is best reserved for maintenance situations where slower timing is acceptable. XC9536-7PC44C requires additional architecture and terminal verification because it is from the non-XL generation. For all candidates, reproduce the design in the current Xilinx or AMD tool flow, perform static timing analysis, and compare the exact DS058 pin and electrical tables before production release.

設計ノート

Treat the PLCC footprint as a pin-sensitive interface rather than a generic 44-terminal grid. Follow the physical terminal-numbering drawing in AMD DS058, preserve pin-1 orientation, and avoid placing vias or tall components where they interfere with the socket or heatsink. Because the package has 34 user I/O pins, maintain consistent, short routing from the device to nearby passive and connector networks, while keeping programming and clock traces away from switching-power nodes.

Use the supply-decoupling network and operating limits defined in AMD DS058, including the specified voltage tolerance and capacitor characteristics. Place bulk and high-frequency decoupling close to the associated power terminals, with a low-impedance return path to the supply or ground plane. Estimate worst-case dissipation from supply voltage, device activity, and I/O loading, then verify that the PLCC and board construction remain within their intended commercial-temperature operating environment.

Do not treat the XC9536XL-5PC44C and XC9536XL-10PC44C as unconditional functional substitutes for the -7 device. Their timing grades differ from the target, so rerun static timing analysis and confirm external setup and hold requirements. The XC9536XL-7PC44I changes the environmental grade, and the XC9536XL-7PCG44C changes the lead-free ordering configuration. In every case, compare the exact terminal and electrical tables before releasing a replacement BOM.

Assign I/O standards only after checking the output and input thresholds required by every connected device. Avoid driving a shared bus from multiple configured outputs, and specify deterministic power-up states for shared-enable or reset signals. Keep sensitive measurement inputs away from the PLCC socket and programming interface, and use ground-plane continuity rather than long ground traces. A short, repeatable layout is especially important when restoring this legacy package in an existing industrial assembly.
